Subaru emerged among the top automakers in crash tests of model-year 2012 cars and trucks conducted by a U.S. insurance industry group.

Subaru, a unit of Fuji Heavy Industries Ltd., is the sole maker to have all of its 2012 models earn the grade, the institute said in an e-mailed statement today.

More vehicles won the ranking this year after manufacturers redesigned roofs to make them stronger in rollovers, the Arlington, Virginia-based insurance group said. Sixty-nine cars, 38 SUVs, 5 minivans and 3 pickups made the list after tests evaluating passenger safety in front, side and rear crashes, as well as rollovers.

“Commitment to protecting people in crashes is evident in the fast pace of design improvements automakers have made during the past year,” the institute said in the statement.

A record number of models qualified for a second consecutive year, Adrian Lund, president of the group, said in the statement. One hundred 2011 model-year vehicles received the top rating, according to the statement.
